Hubble’s Big Reveal: Unearthing the Secrets of a Nearby Earth-Sized World

Hubble’s Big Reveal: Unearthing the Secrets of a Nearby Earth-Sized World NASA’s Hubble Telescope accurately measured LTT 1445Ac, an Earth-sized exoplanet in a nearby triple star system. Initially discovered by TESS, this rocky planet is similar in size to Earth but much hotter. The research enhances our knowledge of exoplanets and their atmospheres. Credit: ESA/Hubble … Read more
